to the driver in the instrument cluster. Driving onto a section of road in the wrong direction
triggers a warning. Traffic Sign Assist detects traffic signs with multifunction camera :
attached at the top of the windscreen. The
data and general traffic regulations stored in
the navigation system are also used to deter- mine the current speed limit.
If a traffic sign that is relevant to your vehicle
is passed, the display of the speed limits and
overtaking restrictions is updated.
The display can also be updated without a
visible traffic sign if:
R the vehicle changes roads (e.g. motorway
exit or slip road)
R a village or town boundary is passed which
is stored in the digital map
R the last traffic sign detected by the camera
has not been repeated Driving systems

Important safety notes G
WARNING
Operating mobile communications equip-
ment while driving distracts you from paying
attention to traffic conditions. This could also cause you to lose control of the vehicle. There
is a risk of an accident.
Use this device only when the vehicle is sta-
tionary.
You must observe the legal requirements for
the country in which you are currently driving when operating mobile communications
equipment in the vehicle.
If it is permitted by law to operate communi-
cations equipment while the vehicle is in
motion, you may only do so if the traffic sit-
uation permits. You may otherwise be dis-
tracted from the traffic conditions, cause an
accident and injure yourself and others.
Excessive levels of electromagnetic radiation
may cause damage to your health and to the
health of others. The use of an exterior aerial
takes into consideration the scientific discus- sion surrounding the possible health risk
posed by electromagnetic fields.
Mercedes-Benz recommends the use of an
approved exterior aerial. This ensures:
R optimal mobile phone reception quality in
the vehicle
R that mutual interference between the vehi-
cle electronics and mobile phones is mini-
mised
An exterior aerial has the following advan-
tages:
R it conducts the electromagnetic fields gen-
erated by a wireless device to the exterior
R the field strength in the vehicle interior is
lower than in a vehicle that does not have
an exterior aerial

Topping up engine oil G
WARNING
Certain components in the engine compart-
ment could be very hot, e.g. the engine, the
radiator and parts of the exhaust system.
There is a risk of injury when accessing the
engine compartment.
As far as possible, allow the engine to cool
down and only touch the components descri- bed in the following. G
WARNING
If engine oil comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.

over the filler neck. Allow the engine to cool
down and thoroughly clean the components
that have come into contact with engine oil
before you start the engine. H
Environmental note
When topping up the oil, take care not to spill
any. If oil enters the soil or waterways, it is
harmful to the environment.
! Only use engine oils and oil filters that
have been approved for vehicles with a ser-
vice system. You can obtain a list of the
engine oils and oil filters tested and
approved in accordance with the
